What to Know

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq

cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but

released in gfx_v9_0_hw_fini(), so the put site has to query

amdgpu_irq_enabled() because the get is skipped on SR-IOV VF.

ras_late_init / ras_fini have no suspend counterpart, so move the

put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a

matching ras_suspend callback that is invoked from

amdgpu_ras_suspend() before disable_all_features(). The get and

put now sit in the same place and check the same condition (not

VF, funcs registered), no refcount querying needed.

An active flag gates ras_fini so the

suspend-then-unload-without-resume path falls into

amdgpu_ras_block_late_fini_default() instead of double-releasing

what ras_suspend already cleaned up.

Drop the cp_ecc_error_irq put from gfx_v9_0_hw_fini(). gfx_v8_0

manages cp_ecc_error_irq locally and is unaffected; no other GFX

generation has this IRQ. (NVD)
